PAPER-MAKING MACHINE;

speeiacauon of Letters Patent. Patented Nov, 1 1, 1913,

To all whom, t may concern.'

Be it known that I, GEORGE D. KILBERRY, a citizen of the United States, and a resident of Worcester, county' of Worcester, and State of Massachusetts, have invented cere tain new and useful Improvements in Paper- Making Machines, of which the `following lis a specification, reference being had to the accompanying drawings, forming la part thereof.

My invention relates to certain improvements in paper making machines, and more particularly to the driving mechanisms of such apparatus as the various units Awhich are used with or comprise parts of a Fourdrinier machine.

It is the object of the present invention t0 so construct and arrange certain parts as to make them more easily adjustable, and to' provide a simple and efiicient arrangement of parts by means of which the units may be readily started or stopped.`

I will describe my invention in the following specification and point out the novel features thereof in appended claims.

Referring to the drawings: Figure 1 is a diagrammatic plan view of a rope drive system as sometimes used in a paper-mill. Fig. 2 is a side elevation also diagrammatic, c-f the parts which are shown in Fig. 1. Fig. 3 is a side elevation of the' driving mechanism for one of the units of the paper making machine, and illustrates an embodiment ofvmy invention. Fig. 4 is an end elevation of the parts which are shown in Fi 3.

` Igiike characters of reference designate corresponding parts in allf the figures.v

10 designates the mill floor upon which the-various elements of the paper-making machiner are mounted. The drivingmachinery is usually under this floor and in the present inst-ance I have shown a rope drive system such as is sometimes used in mills of 'this character, which system comprises a main `engine driven rope sheave 11, from which power is transmitted by means of ropes or cables 12 lte a plurality of countershafts 13 in different fixed positions on each of which is mounted a cone pulley 14.

Under each driven unit of theV apparatus isv a power shaft 15 on which is a cone-pulley 16, disposed oppositell toene of the pulleys 14, and each pair o nected by a belt 17.

cone-pulleys is 'con- So in uch of the apparatusv as has now been pointed out is in common use and needs no further description. It is to be understood that the usual means are provided for shifting the belts 17 to vary'the speed of the 'driven units relatively to that of the engine which drives them. t

My invention is preferably applied to each of the driven units, but as it is substantially the same for each of the units, I will describe but one of them.

Instead of'mounting the countershaft 15 in fixed bearingsaccording to the present practice, I mount it in bearing blocks 20 which are vertically slidable in movable frames 21, which frames are themselves `horizontally slidable upon longitudinally disposed channel irons 22. The bearing blocks 20 run in guides in the frames 21 and their vertical position in the frames may be varied and maintained by means of adjusting screws 23-23 which are threaded through parts of the framesV andv are provided with cheek nuts 24.

In order to move the frames 21 horizontally, threaded adjust-ing shafts 25 engage' with threaded. lugs 26 which are parts of the frame. These adjusting shafts are held against longitudinal movement by some suitable means such as collars affixed to them on opposite sides of a stationary bearing. -On each of them is a sprocket wheel 27. These are connected by a chain 28 so that the two shafts will rotate together and thus move the two frames 21 a like amount.

29 is a hand-wheel on the end of the shaft 25, by means of which it may be turned. It is obvious that' by means of this arrangement the shaft 15 may be shifted either up or downor back and forth at will. On the 'shaft 15 is also supported a pulley 30 which makingmachine, such \for example, as one of the drier rolls 34.

' l 35 is an idler running against the belt 31.

Itis mountednear the upper ends of arms 36 which form a art of a bell-crank lever which is mounted in bearings 37 in the mov'- able frame 21, and the other arm of which is desi nated by 38.

A ove the floor 10 near the driven unit is y a hand lever 40 pivoted in a support 41 and connectedv by an arm 42 and connecting rod 43 with the end of the arm 38 of the bell crank-lever. An ordinary rack and pawl mechanism may be'provided to hold these connected parts in the desired positions. The lever 40 is offcourse rovided for the purpose of shifting the posltion of the idler 35.

The operation of this device is as follows: The shaft rotates whenever the engine is running. Thebelt 31 is so loose however that the sheave 32 will not bel driven by it unless the idler 35 is moved over to take up the slack of the belt 31.` Thus this driven mechanism may be started or stopped by a mere movement of lever 40 and this result accomplished by an extremely simple mechanism which does awaywith the usual complicated and troublesome friction clutches.

The two beltsV 17 and 31 which are in operative relation with the shaft 15, run in different directions therefrom. The mechanisms which I have before described for shifting the position of shaft 15 either ver- 7tically or horizontally or both, makes it possible to adjust the tension on both of these belts in a very easy manner and it isy to be noted that these adjustments may be made while the machine yis running. Heretofore such belt adjustments necessitated the shutting down of the entire machine with the attendant loss of time and output which in a large high-speed Fourdrinier apparatus is a serious loss. l

The belll crank lever is pivoted in the movable frame with the shaft 15, so that horizontal movements of the shaft 15 will not materially aifcct the adjustment of the idler 35 in relation to the belt 31. It is also of importance that this arrangement has a bias to safety, forin case of breakage of any of theidler actuating mechanism, the idler will fall away from the belt and the unit which it `controls will stop.

I have devised this apparatus for the express purpose of overcoming some Iof the disadvantages attendant upon the use of lsuch mechanisms as have hitherto been available for paper making machinery. Although I have so described my invention, it is obvious that it is also applicableto use with machines used for other purposes.

What I claim is:

1. In a paper making machine comprising a plurality/of units, the combination with one of said units, cfa ower shaft, a beltin operative relation t ereto, means for shifting 'the position of the shaft in one direction, and other means for Ashifting the position of the shaft in another direction, to vary the tension of the belt.

2. In a paper making machine comprisin a pluralit of units, the combination wit one of sai units, ofa power shaft, two belts in operative relation thereto, said belts movin indifferent directions, manual means for shifting ythe position ofsaid shaft back and forth in one plane, and other means for shifting the position of the shaft up and down in a transverse plane to thereby varythe tension of the belts.

3. YIn a paper making machine comprising a pluralit of units, the combination with one of said units,` of a power shaft, a movable frame in which said shaft is mounted, a loose belt between the unit and the power shaft, and an idler pulley, swingingly mounted upon said movable frame, for

tightening said belt to thereby cause the slidable frame in whichthe power Shaft is mounted, means for adjusting the position of the power shaft relative to said frame in vertical directions, av driving belt running to said power shaft from one direction, a loose connecting belt running from the pulley on the power shaft to the pulley on the unit Shaft in another direction; an idler pulley arranged to engage with said loose belt, said idler pulley being swingingly mounted ingthe slidable frame, a hand lever near the unit, and connections between said lever and the idler pulley whereby the position of said idler pulley may be rshiftedlat will to start or stop the unit.`
